MILKINc-Mncnmn CLAW.

Application tiled November 9, 1917. Serial No. 201,025. "N-

To 'all whom t may concern: Be it known that I, MEREDITH LE1TcH,a

citizen of the United States, .residing at Poughkeepsie, county ofDutchess, and State oNew York, have invented a new 'and usefulImprovement, in Milking-Ma-l chine'Claws, of which the following is a l*j full, clear, and exact description, reference being had to theaccompanying drawings,

which' form a part of this specificatlon.

" My invention relates -to that class of milking machines in which theteat` chambers of a plurality of teat cups, usually a setA of four, areconnected,v by a manifoldorclaw,

to a milk pipe, The invention is applicable to claws used in connectionwith singlel chamber teat cups and to claws used in connection withdouble chamber teat cups, the latter including those wherein connectionis afforded from-the pulsation chambers ofv all four teat cups to asingle p'lsation pipe and those wherein Vthe pulsation chambers of twoteat cups are vconnectedto one pulsation pipe and the pulsation chambersof the other two teat cups to another pulsation 1 e. l p Irihe object ofthe invention is to so construct the claw and the connection between thesame and the milk pipe leading'to the pail thatthe separable parts maybe readily dissociated to permit the milk passage of the claw to becleaned and to permit, also,

if desired, the thorough cleaning of the teat chamber of each cup andthe p-ipe leading thereto without detaching the same from theclaw.

In the embodiment chambers of two teat cups to one pulsation pipe andthe pulsation chambers of the other two teatV cupsto another pulsationFigure 1 is a diagrammatic view of a complete installation-.- Q

suction in pipes d f la and pulsations in each of the pipes f and g, thepulsations b eing alternate, in that when the relative pressure rises inone pipe f or g it drops in the other. A pulsator. so constructed andconnected and adapted to so operate is shown in a patent issued tomevAugust A29, 1916,. No.- 1,196,001; but the pulsator, its connections,and its -mode of operation form no part of the present invention and thestructure is therefore not The `claw bodyl is provided with twoparallel, lateral, independent passages m and n communicatingrespectively with nozzles z' and j, which are on the claw and areadapted for connection respectively with the pulsation pipes f and g.Integral with the claw are nipples o, o, and p, p, the two formercommunicating with passage m and the two latter with passage n. Thepulsa-- tion chambers of teat cups "1", 'fr' and 8,8 are connected, bypipes thtand u, u respectively, with the respective nipples o, o and p,p.

The body of the claw is provided with a hollow milk chamber v open atthe bottom. Opening in the side walls of the milk chamber are fourpassages w, which'communi- 90 cate respectively with four nipplesmintetion respectively with the four milk tubes y connected with theteat chambers of the respective teat cups. ,p5

Around the circular bottom-of the claw.v body is a bead z and in thecenterof the milk chamber, depending from its roof, an inverted pedestallhaving its bottom ,f'

A bottom member 11, of flexible and elastic f3', material, as, forinstance, soft rubber, isgf-r formed to it closely around the bead andThe milk pipe k is preferably integral withlo the bottom 1l so that thelatter completely dig, seals the bottom of the milk chamber except@ forthe opening therein communicating with the milk pipe c. i

from the claw body, Whenso removed it exposes the entire milk chamberfor inspec* tion and cleansing. If desired, a brush may 'a and tend toforce it into the milk chamber 'v'. The pedestal l0 supports the centerof the bottom against this pressure and allows it to be made with amuchv lighter wall.

Having 'now fully described my invenf tion, what I claim and desire toprotect by Letters Patent is: 1

1. A-'milking machine claw comprising a body having a milk chamber,nozzles com- -municating therewith adapted for connesy tion with teatcups, and a flexible and elas-l tic chamber bottom having a milk pipeadapted for communication with amilk pail. 2. A milking machine clawcomprising a body having a hollow' chamber and a detachable chamberbottom adaptedtobe held in place by its own elasticity.

3. A milking .machine claw comprising a body having a hollow chamber anda closure for the body having formed integral therewith a milk tube,said closure and tube being of flexible and elastic material.

4. A milking machine claw comprising a body having an open bottomedchamber and four milk passages extending through the body and openinginto theI chamber wall, and a flexible and elastic member acting as aclosure for said chamber and detachable to permit cleansing of saidchamber andV passages.

5. A milking machine claw comprising a body having a hollow chamber andan inte- .v rior depending pedestal having a free lower pedestal.

A milking machine claw comprisinga miauw body having a hollow chamber, a centrally disposed pedestal inthe chamber, and a de- -tachable bottom adapted to beheld in place byits own elasticity and supported, against collapsing, by the pedestal.

pedestal depending from the top'of the body and having a free lower end,and a flexible and elastic chamber bottom adapted to beA held by its ownelasticity in position on the body and against the free lower end ofthe' pedestal.- y

8. A milking machine claw .comprising a body having a hollow milkchamber opening downwardly, Van inverted pedestal disposed centrally inthe chamber whose lower end is approximately level with the lower edgeof the chamber, and a flexible elastic bottom attachable to the edge ofthe chamber and adapted to be supported by the pedestal.

9. A milking machine claw comprising a body having a hollow milk chamberopening downwardly, an inverted pedestal disposed centrally in thechamber whose lower end is'approximately level with the lower edge ofthe chamber, and a flexible elastic a bottom attachable to the edge ofthe cham-` ber and provided with an integral milk tube adapted forconnection with a source of suction, said pedestal adapted to supportthe bottom during operation against inward collapse by outsideatmospheric pressure.

10. A milking machine claw comprising a y body provided with a pulsationpassage adapted for connection with la pulsation tu e and with nipplescommunicatin with said passage and adapted for connectlon with the vpulsation chambers of teat cups and provided also with an independentmilkchamber and with nipples communicating with said chamber and adaptedfor connection with the teat chambers of teat cups, and a flexible andelasticchamber bottom havin a milk pipe adapted for communication with amilk pail.

In testimony of which invention, I 'have hereunto set. my hand, atPoughkeepsie, N'. Y., on this 3d day of Nov., 1917.
